FIG. 3 shows a conventionally used interleaf paper winding device. In this winding device, a disc-shaped guide 3 is attached to a shaft 2, and the shaft 2 is rotated by a driving force of a motor 4 to wind an interlayer paper. However, this conventional winding device has a problem that it is not easy to remove the interlayer paper from the shaft 2 after winding the interlayer paper. This is because the shaft 2 is fixed to the drive shaft of the motor 4, which makes it difficult to handle, and the tightening force of the interlayer paper makes it difficult for the shaft 2 to come off.

In the conventional winding device, the shaft 2
Due to the inertia of the guide 3, it is difficult for the interlayer paper to wind up, and the interlayer paper sags during winding, or the interlayer paper is cut due to being pulled too strongly. Therefore, the present invention has been made to solve the above problems, and its purpose is to make it easy to adjust the tension when winding the intercalation paper, resulting in slack of the intercalation paper or tearing of the intercalation paper. It is an object of the present invention to provide an interlayer paper take-up device that can solve the above problem, and that can easily remove the interlayer paper after winding and is easy to handle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 shows the construction of an embodiment of an inter-layer paper winding device according to the present invention. The winding device of this embodiment includes a support base 10, a support plate 12 provided upright on the support base 10, a drive motor 14 having a drive shaft horizontally attached to an upper side surface of the support plate 12, and a drive motor 14.
Shaft 16 connected to the drive shaft of the shaft 16 and a cylindrical winding portion 18 coaxially fixed to the end of the shaft 16.
And a pin mounting body 20 detachably mounted in a socket shape from the outer end surface of the winding portion 18, and a support plate 12
And an inter-leaf paper guide 24 attached to an arm 22 provided so as to extend forward in the drawing direction of the inter-layer paper.

As shown in FIG. 1, the shaft 16 is rotatably supported by passing through the support plate 12 in the thickness direction, and one end of the shaft 16 is fixed to a slip clutch 26 connected to a drive shaft of a drive motor 14. To be done. Further, the other end of the shaft 16 is formed in a disc shape having a diameter larger than the shaft diameter,
The winding portion 18 is fixed by bringing one end surface into contact with the disc portion. The winding unit 18 is supported by the shaft 16 and is mounted horizontally. The winding unit 18 of the embodiment is made of plastic.

The pin mounting body 20 has a winding portion 18
Has a ring portion 20a that is detachably attached to the other end and a pin 30 that is erected with the base end portion embedded in the ring portion 20a. In the embodiment, the other end of the take-up portion 18 is formed with a slightly reduced diameter, and a steel ring 32, which is externally inserted into this reduced diameter portion and is lightly press-fitted, is fitted to the inner circumference of the ring portion 20a. That is, the pin attachment body 20 is attached to the winding portion 18 by lightly press-fitting the ring portion 20 a into the outer end surface of the winding portion 18.

The pins 30 are arranged so as to make elastic contact with the outer peripheral surface of the winding part 18 when the ring part 20a is mounted on the winding part 18, and a plurality of pins 30 are arranged at equal intervals in the circumferential direction of the winding part 18. Set up a book. In the embodiment, four pins 30 are fixed to the ring portion 20a in the circumferential direction. As shown in FIG. 1, the pin 30 has a length such that the tip of the pin 30 extends to the base end side of the winding portion 18 when the ring portion 20 a is mounted on the winding portion 18. FIG. 2 shows a state in which the pin attachment body 20 is viewed from the side surface direction. It can be seen that the four pins 30 are attached to the ring portion 20a at equal intervals. It can also be seen that the steel ring 32 is provided concentrically with the ring portion 20a.

The arm 22 extends forward from the support plate 12 as shown in FIG. 2 and is bent at its front end into an L shape at a front end thereof at a right angle to the traveling direction of the interlayer paper. Set up. The guide 24 is movably mounted on the arm 22 at the front end of the L-shaped bent arm 22. The guides 24 are adjustable according to the width of the interlayer paper, and a pair of guides 24 are arranged to guide both side edges of the interlayer paper.

When the interlayer paper winding device of the above-mentioned embodiment is used, the pin mounting body 20 is externally mounted from the outer end portion of the winding portion 18 as shown in FIG. . At the time of starting the winding, the interlayer paper is wound so as to be sandwiched between the pin 30 and the outer surface of the winding portion 18. The drive motor 14 rotationally drives the winding unit 18 with a constant rotational driving force to wind the interlayer paper. As the interlayer paper is rolled up, a tightening force acts on the pin attachment body 20, and the pinned body 20 can be prevented from rotating and wound up. By providing the slip clutch portion 26, slippage occurs automatically when the rotational driving force of the drive motor 14 exceeds a certain level, and winding can be performed without applying excessive tension to the interlayer paper. it can.

FIG. 2 shows a state in which the interlayer paper 40 is wound around the winding section 18. The interlayer paper 40 is guided by the guide 24 and is sequentially wound up. When the winding of the interlayer paper is completed, the pin mounting body 20 is pulled out from the winding section 18, and the interlayer paper 40 and the pin mounting body 20 which have been wound are removed from the winding section 18. Since the pin 30 is in contact with the outer surface of the winding portion 18, the pin mounting body 20 can be easily pulled out from the winding portion 18.
Then, the pin mounting body 20 pulled out together with the interlayer paper 40 is easily detached from the interlayer paper 40 because the pin 30 bends inward. In this way, after the pin mounting body 20 is removed, the pin mounting body 20 is mounted on the winding section 18 again as shown in FIG. 1, so that the next winding operation can be started.

As described above, according to the inter-layer paper winding device of the present invention, the pin mounting body 20 is used for the winding portion 18.
Since the pin 30 is detachably attached to the outer surface of the sheet, the work of removing the inter-layer paper after winding can be extremely facilitated. As a result, it becomes possible to operate the inter-layer paper efficiently even when the winding operation of the inter-layer paper is continuously performed. Further, in the winding device of the embodiment, by providing the slip clutch 26, it is possible to prevent excessive tension from being applied to the interlayer paper at the time of winding, and the interlayer paper can be removed by winding with a constant winding force. It is possible to solve problems such as cuts and winding not being performed smoothly.
